If I am correct, it should cost around the same as any awesome RTS, which should be a one time only of 50 bucks for the copy, I don't think they plan on charging monthly on online MMO or skirmish or anything.

Hope someone more suitable ca give more specific information, just confirming this isn't free, but I'm sure it will be worth the money.

You're probably looking at the standard price range for new games. As mentioned, 50 bucks sounds appropriate. It certainly won't be free (legally anyways
For my part, I pay for my games. If it's not worth paying for, it's not worth playing. That's not to say that freeware is bad, it's just that I won't pirate my games. I intend to support developers who actually strive to create excellent titles.

From the 50$ you get in a store like Besbuy or Wallmart, the store keeps around 8-10$. The manufacturing of that good looking game box, DVDs and manual takes another 5-10$ - depending on how fancy the Game box is. Usually Publisher would take at least 50% of what`s left. And in the end developer would get around 8$-10$ after years of hard work and majority of investment

We are really pushing DoF to be soled online as well as retail. Download size of the final game should be under 1.2GBs making it quite an easy download. And manufacturing and retail fees are almost nil.
